Answer:
She will save 62.40
Step-by-step explanation:
First find the total amount she makes
hours times hourly rate
19.5 * 12.80
249.60
She saves 1/4 of this, so multiply by 1/4
1/4 * 249.60
62.40
She will save 62.40

Step-by-step explanation:
7x²+14x+7
(7x+7 )(x+1 )
7x²+7x+7x+7
7x²+14x+7
Answer:
y= -2x+23
Step-by-step explanation:
Subtract 2x over
Given: F=ma. To solve for a, we isolate a on one side of this equation. To do this, divide both sides of F=ma by m. Then F/m = a.
Thus, if m=10 units, the acceleration is a = F/10 units. Looks as tho' you were given the numeric value of F but did not share that value here.
Solving F=ma for m: m=F/a. Thus, if F=25 units and a=5 units, m=25/5 units, or m=5 units.
